BM-5型色度计是国内彩色电视机厂常用的测光、测色仪器,为了帮助大家正确使用该仪器,现将该仪器的使用情况作一简要说明。 BM-5型色度计是日本东光公司生产的小型非接触式测色、测光仪器,由微处理机进行演算处理,直接由数字显示亮度值(cd/m~2)和色度坐标(x、y),并可在CIE 1931色度图上直接找出色度坐标。当测量白场色温时,可直接在CIE 1931色度图普朗克轨迹等温线上读出色温和MPCD标尺值,并进而求出颜色主波长、饱和度等。该仪器还具有自动调零、
BM-5-type colorimeter is commonly used in domestic color TV factory metering, color measurement equipment, in order to help you use the instrument correctly, now the use of the instrument as a brief description. The BM-5 colorimeter is a small non-contact colorimetric and photometric instrument produced by Japan’s Toko Corporation. It is operated by a microprocessor and directly displays the luminance values (cd / m ~ 2) and the chromaticity coordinates (x, y) and find the chromaticity coordinates directly on the CIE 1931 chromaticity diagram. When measuring the color temperature of a white field, the color temperature and the MPCD scale value can be directly read out on the CIE 1931 chromaticity diagram Planck’s locus isotherm, and then the dominant color wavelength and saturation are obtained. The instrument also has automatic zero adjustment,
